Clinically, 5T4 is highly expressed in approximately 80% of solid tumors while being restricted in normal adult tissues, making it an ideal target for tumor immunotherapy that has been exploited in the development of vaccines (Trovax), antibody-drug conjugates (ADCs), CAR-T\/TCR-T cell therapies, and superantigen fusion proteins (Naptumomab), and is closely associated with cancer stem cell properties and poor prognosis in multiple malignancies.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"UA BIOSCIENCE","offers":[{"title":"25μg","offer_id":42887927464011,"sku":"UA016104-25μg","price":430.0,"currency_code":"USD","in_stock":true},{"title":"100μg","offer_id":42887927496779,"sku":"UA016104-100μg","price":850.0,"currency_code":"USD","in_stock":true},{"title":"500μg","offer_id":42887927529547,"sku":"UA016104-500μg","price":2240.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/AntBioImage_76586111-399a-4522-b240-d1bde9279396.png?v=1783774835","url":"https:\/\/www.antbioinc.com\/products\/biotinylated-tpbg5t4-hisavi-tag-protein-human-ua016104","provider":"AntBio","version":"1.0","type":"link"}
